2 Wrapping cold food in aluminum foil is safe

The researchers also mentioned that aluminum wrapping of cold food is safe as the leaching was only observed upon heating. It did not make a difference on which side the food was placed, the shiny or dull side.
Unusually high levels of aluminum in the body can cause mineralization of bone, matrix formation, and parathyroid and negative bone cell activity. The most common symptom of high levels of aluminum in the body and the dangers of aluminum foil is hypercalcemia or high levels of calcium in the blood.

3 Aluminum mixes with calcium and weakens bones

High aluminum levels in the body alter bone mineralization, matrix formation, as well as parathyroid and bone cell activity. Ironically, one of the most common signs of excessive aluminum accumulation is hypocalcaemia or high calcium levels in the blood.
The reason for this happening is because aluminum in the body restricts calcium deposits in bone thus causing an increase of calcium in the blood. This in turn depresses PTH secretion which is secreted by the Parathyroid hormone. The chronic aluminum toxicity which then builds up retards bone mineralization which then causes osteoporosis.
